My experience in education has allowed me to develop a deep understanding of how students learn and the various approaches that can be used to facilitate their learning. I believe in creating a positive and inclusive learning environment that encourages students to ask questions and engage with the material. I work closely with my students to understand their individual learning styles, strengths, and challenges to tailor my approach accordingly. I also place a strong emphasis on building strong relationships with my students, which fosters trust and creates a supportive learning environment.
